UNITED STATES PATENT OFFICE.

WILLIAM H. PLANE, OF CHICAGO, ILLINOIS.

TOBACCO-PIPE.

To all whom it may concern:

Be it known that I, WILLIAM H. PLAN-E, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented certain new and. useful Improvements in Tob acco-Pipes, ofwhich the following is a specification.

invention relates to tobacco'pipes, and the object of my invention is toprovide a pipe of such improved construction that the nicotin will beseparated from the smoke in its passage from the bowl of the pipe to thesmokers mouth and will be deposited in suitable recesses provided toreceive it.

A further object is to provide a pipe in which the smoke shall beconsiderably cooled before it reaches the mouth.

Further objects are, to provide a pipe as mentioned which shall beformed 1 of few parts which may be readily taken apart and easilycleaned and as readily reassembled, and to provide a pipe having thecharacteristics mentioned which shall present a neat appearance notunlike that of theordinary pipe. Other objects will appear hereinafter.With these objects in view my invention consists generally in a pipecomprising a bowl, a stem formed thereon having a cylindrical bore, acore arranged within said bore and having a tortuous passage, portionsof which are arranged to constitute pockets to receive and hold thenicotin which is separated from the smoke as it passes through saidpassage.

My invention further. consists in the various novel details ofconstructionand arrangements of parts all as will be fully describedhereinafter, and particularly pointed out in the claims.

My invention will-be more readily under stood by reference to theaccompanying drawings forming a part of this specification and in which,

Figure 1 is a longitudinal section of a pipe embodying my invention inits preferred form, Fig. 2 is a side elevation thereof Fig. 3 is a planview of the core removed from the stem and Fig. 4 is a cross section onthe line ac-w of Fig. 3. I

Referring to the drawings, 1 indicates the bowl of the pipe which may beof any preferred form and is provided with the stem 2 havin acylindrical bore 3. The bore 3 is much larger than the usual bore inorder to receive a core 4, which, being provided with Patented Feb. 18,1908.

a tortuous passage and a plurality of nicotin pockets constitutes .abaflie for the smoke. The core. 4 is substantially cylindrical, fittingsnugly within the bore 3 and is provided with a plurality of annulargrooves 5 spaced at. equal distances apart and forming with the bottomwalls of the stem 2 nicotin pockets 6. The portions 7 of the coreintermediate of the grooves 5, fit the bore snugly, and a smoke channelof passage is formed by connectingthe grooves 5 with longitudinallydisposed grooves formed In the portions 7. Any number of these groovesmay be provided in the portions 7 but I find two. a sufiicient numberand prefer to arrange them in the upper side of the core so as not tointerfere with the nicotin collected in 'the bottom of the pockets 6.The grooves may be disposed in any suitable manner, but I preferthatillustrated in the drawings. The grooves 8 extending from the bowl ofthe pipe to the first nicotin chamber 6 are preferably straight and arearranged diametrically opposite to each other in 'the side of the firstportion 7. The other portions 7 are each provided with a pair of grooves8 forming. an exit from the sides of eachpocket and converging into onebefore reaching the top of the next succeedin pocket. By thisarrangement the triangu ar portion between each pair of grooves forms abaffle 7 for the smoke emitting from the preceding grooves. This causesthe nicotin to be deposited in the grooves 5 and to be finally collectedin the bottom of the pockets.

.The grooves forming a tortuous passage are arranged upon the surface ofthe core keeping the smoke in contact with the walls of thestem. Thiscauses the smoke to be cooled to a considerable degree before reachingthe mouth. The end of the core is threaded into the end of the stem 2 asat 9 and is provided with an enlarged portion 10 which forms anextension of the stem. The portion 10 is provided with a socket 11 toreceive the end of the mouth piece 12. 13 indicates a small bore leadingfrom the last groove 5 to the socket 11 and communicating with the bore14 of the mouth piece.

The device is readily dismembered for cleaning. To this end the portion10 carrying core 4 is unscrewed and withdrawn from the stem 2, afterwhich the bore may be cleansed as well as the grooves in the core.Further the device presents a neat appearance not unlike that of theordinary pipe.

The principal difference bein a slight enlargement in the diameter of te stein.

Having described my inventionwhat I claim as new and desire -to secureby Letters Patent is;

1. Ina device of the class described, a bowl, and'a' stem having acylindrical bore,

in combination with a cylindrical core fitting snugl within said bore,said core having a plura it 1 of annulargrooves spaced at equaldistances apart thereon and a pair of grooves forming an exit from eachsaid annular grooves and converging into one before dis charging intothe next succeeding groove and a mouth piece at theend of said core,substantially as described.

2. In a device of the class described, a bowl and a stem having acylindrical bore, in

avep'ee combination with a cylindrical core, arranged to fit within saidbore, said core having a torg signed my 30 presence of Witnesses:
